MaskRay added a parent revision: D72220: [X86] Support function attribute "patchable-function-entry".
MaskRay added a child revision: D72222: [Driver][CodeGen] Add -fpatchable-function-entry=N[,M].

This feature is generic. Make it applicable for AArch64 and X86 because
the backend has only implemented NOP insertion for AArch64 and X86.
